| description | The two fruit varieties growth and development dynamics of lulo (Chonto grueso and Criollo) was studied under conditions of Pachavita municipality, of Boyacé department. Dry biomass, the Absolute Growth Rates (AGR) and Relative Growth (RGR) were evaluated. The two fruits varieties have a simple sigmoid growth, with three phases which were described as: FI (cell division), FII (cell elongation) and FIII (maturation). The Chonto grueso variety showed an exponential increase in the AGR covering the FI and part of the FII, up to 78 days after anthesis (DAA) when it reached its highest value of 0.117 g/day, and a rapid dw mass gain, up to this point, then decreased until harvest. The Criollo variety showed a slow increase in the FI, which was progressive until reaching its peak at 128 DAA, accumulating 0.107 g/day, which meant a slower increase in size over time, demonstrating greater initial landfill power in Chonto grueso variety, regarding the Criollo variety in terms of dry matter. The RGR for Chonto grueso variety showed a slow decline in FI, drastically reduced in FII and slowly in the FIII; while the Criollo variety showed a gradual and steady decline to 140 DAA. It was established for the Chonto grueso variety in FIII and in general for the Criollo variety, a low rate of change in size per unit initial size. |

Se estudió la dinámica del crecimiento y desarrollo del fruto de dos variedades de lulo (chonto grueso y criollo) bajo las condiciones del municipio de Pachavita (Boyacá). Se evaluaron la biomasa seca y las tasas de Crecimiento Absoluto (TAC) y de Crecimiento Relativa (TRC). Los frutos de las dos variedades presentaron crecimiento tipo sigmoide simple, con tres fases que se describieron como: FI (división celular), FII (elongación celular) y FIII (maduración). La variedad Chonto grueso mostró un incremento exponencial en la TAC, que abarcó la FI y parte de la FII, hasta los 78 días después de antesis (dda), cuando alcanzó su mayor valor, de 0,117 g/día, y una rápida ganancia de masa seca hasta este punto, luego disminuyó hasta la cosecha. La variedad Criollo mostró un aumento lento en la FI, que fue progresivo hasta llegar a su máximo valor a los 128 dda, acumulando 0,107 g/día, lo que implicó un aumento de tamaño más lento en el tiempo, demostrando mayor poder vertedero inicial en la variedad Chonto grueso, respecto a la variedad Criollo, en términos de materia seca. La TRC para la variedad Chonto grueso mostró una lenta disminución en la FI, reduciéndose drásticamente en la FII y lentamente en la FIII, en tanto que la variedad Criollo mostró un descenso gradual y constante hasta los 140 dda. Se estableció, para la variedad Chonto grueso en la FIII, y en general para la variedad Criollo, una baja tasa de variación del tamaño por unidad de tamaño inicial.
